In 161 patients, aged 19-75 yr and subjected to epidural anesthesia for extracorporeal shock wave lithotripsy, the relationships between the spread of lumbar epidural analgesia with 10 ml of 2% mepivacaine and age, height, weight, weight/height ratio, and body mass index were studied. The highest correlation was found between the age and the spread (r = 0.67, P < 0.001). The next higher correlation was found between the height and the spread (r = -0.32, P < 0.001). The lowest but a statistically significant correlation was found between the body mass index and the spread (r = 0.16, P < 0.05). A strong inverse linear relationship was found between the age and the epidural dose requirement (r = -0.59, P < 0.001).
对161例年龄在19至75岁之间、接受硬膜外麻醉以进行体外冲击波碎石术的患者，研究了10毫升2%甲哌卡因产生的腰段硬膜外镇痛范围与年龄、身高、体重、体重/身高比及体重指数之间的关系。发现年龄与镇痛范围之间的相关性最高（r = 0.67，P < 0.001）。其次是身高与镇痛范围之间的相关性（r = -0.32，P < 0.001）。体重指数与镇痛范围之间的相关性最低，但具有统计学意义（r = 0.16，P < 0.05）。发现年龄与硬膜外剂量需求之间存在强烈的负线性关系（r = -0.59，P < 0.001）。
